Firefox ESR 38.4.0 Download

Firefox ESR is intended for companies, public institutions, universities and other organizations that manage and distribute the browser centrally. Originally there should be such a version after five Releases or 30 weeks connected to a support for a total of 42 weeks. The current plan is aimed now at an annual version, which receives all the required security updates at this time.Changes to its basic functionality for Web and extensions but it should not be more than nine release cycles or 54 weeks.

As always, the new version also includes improvements in memory usage that has been made under the MemShrink project. Add-ons for example, require significantly less memory since Firefox 15 and run faster than with previous Vesionen under certain circumstances, such as developer Nicholas Nethercote writes in his blog.

The new version of the Extended Support Release of Firefox based on the standard version of Firefox 38 and was together with this updated and released. Accordingly, there was also a version jump.
